Last year, at Unite LA, we released a video showcasing the brand-new Visual Effect Graph in action through a First-Person Game walkthrough, using Unity 2018.3. This demo was rendered using the High-Definition Render Pipeline and showcases High-Definition assets, lighting, and effects.
去年，在Unite LA，我们发布了一个 视频， 展示了全新的视觉效果图， 该 视频 通过使用Unity 2018.3进行的第一人称视角游戏演练进行了展示。 该演示是使用“高清渲染管线”渲染的，并展示了高清素材资源，照明和效果。
This year, Visual Effect Graph will come out of preview with Unity 2019.3. In order to explore how this project was made, we upgraded the effects to take full advantage of the latest features and released and documented the Spaceship demo project. You can already download, open and learn from it, starting today, using Unity 2019.2.
今年，Visual Effect Graph将在Unity 2019.3。中脱颖而出。 为了探索该项目的制作方式，我们 升级了效果以充分利用最新功能， 并发布并记录了太空飞船演示项目。 从今天开始，您就可以使用Unity 2019.2。下载，打开并从中学习。

用爱(和Unity)制作的Triple-A游戏特效 (Triple-A Game VFX, made with love (and Unity))
All effects from the Spaceship Demo are made using Visual Effect Graph, from simple environmental VFX to more complex Augmented Reality and Holographic UI, HUD, to a gorgeous Reactor Core effect. Here are some eye-candy screenshots of the environments and effects you will encounter in the demo.
太空飞船演示中的所有效果都是使用 视觉效果图制作的 ，从简单的环境VFX到更复杂的增强现实和全息UI(HUD)，再到华丽的Reactor Core效果。 这是您在演示中会遇到的环境和效果的令人眼花dy乱的屏幕截图。
为生产而创作 (Authored for production)
The spaceship demo features many effects during its walkthrough. All these effects have been authored and optimized in-game production conditions with performance in mind, targeting 33.3 ms (30 fps) on Playstation 4 (base) at 1080p. All the effects are taking advantage of the many optimization settings we implemented in Visual Effect Graph and High Definition Render Pipeline.
太空飞船演示在演练过程中具有许多效果。 所有这些效果都是在创作和优化游戏制作条件的过程中考虑到性能的，在1080p的Playstation 4(基本)上目标为33.3毫秒(30 fps)。 所有效果都利用了我们在 视觉效果图 和 高清渲染管线中 实现的许多优化设置 。
Half-Resolution Translucent Rendering renders selected transparent particles at a lower resolution, increasing rendering performance by 4 (at the expense of little blurriness in some rare cases). We used it mostly for big, lit particles that are present in the foreground as their texel/pixel ratio is rather low, the loss in resolution is not noticeable at all.
半分辨率半透明渲染 以较低的分辨率渲染选定的透明粒子，从而将渲染性能提高了4 倍 (以在某些罕见情况下几乎没有模糊性为代价)。 我们主要将其用于前景中存在的大而明亮的粒子，因为它们的纹素/像素比很低，分辨率的损失一点也不明显。
Octagon Particles is an optimization of quad particles and enable the corners of the particles to be cropped. where the pixels are often found transparent (invisible cost). Particle corners are often transparent, but the overlapping of these transparent areas result in unnecessary calculations. Cropping out these sections can optimize the scene up to 25% in situations where there is lots of overdraw. There is also the benefit of reducing the resolution of the translucent sections when they can’t be cropped away.
八边形粒子 是对四边形粒子的优化，可以裁剪粒子的角。 通常会发现像素是透明的(看不见的成本)。 粒子角通常是透明的，但是这些透明区域的重叠导致不必要的计算。 在存在大量透支的情况下，裁剪这些部分可以使场景优化高达25％。 当无法切掉半透明部分时，还有一个好处是降低其分辨率。
Simplified Lighting model: Simple Lit for HD Render Pipeline enables disabling properties of the BRDF – Diffuse Lighting, Specular Lighting, Shadow and Cookie Reception, and Ambient Lighting. By selecting only the features you want to see, you can decrease the lighting computation cost to close to none. For instance, particles can be lit using only Light Probes by selecting a Simple Lit Translucent Model, then disabling everything except ambient lighting. This optimization was chosen for many environment effects that did not require a lot of high-frequency lighting.
简化的照明模型 ：HD渲染管线的简单点亮功能可禁用BRDF的属性-漫射照明，镜面照明，阴影和Cookie接收以及环境照明。 通过仅选择要查看的功能，可以将照明计算成本降低到几乎没有。 例如，可以通过选择“简单点亮半透明模型”，然后禁用除环境照明之外的所有内容，仅使用“光探测器”来照明粒子。 选择此优化的原因是不需要很多高频照明的许多环境效果。
